COUPLING.

Specification of Letters Patent.

Patented July 19, 1910.

Application filed August 10, 1908. Serial No. 447,718.

To all whom 'it may concern:

Be it known that I, HARRY T. KRAKAU, of Cleveland, Cuyahoga county, Ohio, have invented a new and useful Improvement in Couplers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 shows in plan View a coupler constructed in accordance with my invention; Fig. 2 is a side elevation partly in vertical section and showing a portion of a buffer engaged with the coupler head; Fig. 3 is a rear end view of the shank.

As shown in the drawings, the couplerhead has on its top surface an upwardly projecting lug 1 extending upwardly above the bulfer-horn 5 and having lateral bearing surfaces, and adapted to engage a slot or recess in the bottom of a buffer 5, so that when the coupler and buffer are mounted for radial movement the coupler shank and buffer-shank will be maintained in alinement during their lateral movements.

The coupler shank has at its rear end a vertically extending enlargement 2, provided with transverse holes 3 through which are passed the bolts by which the coupler shank can be attached to a rearwardly extending member or shank extension. The enlargement of the rear end of the coupler shank enables these holes to be spaced apart and to afford a very strong connection for the shank. At the middle portion of the coupler-shank, I form holes 4 which are employed for the attachment of a wearing shoe to prevent wear upon the shank.

I claim A car coupler having on its top a guiding lug projecting upwardly above the buffer horn, and havin side bearing surfaces and an overlying buer member having a recess in its under side engaged by the side bearing surfaces of' the lug to cause the coupler and buffer member to move laterally in unison.

In testimony whereof, I have hereunto set my hand.
